Descriptions

In the Linux kernel, the following vulnerability has been resolved:

ksmbd: fix slab-out-of-bounds in smb_strndup_from_utf16()

If ->NameOffset of smb2_create_req is smaller than Buffer offset of
smb2_create_req, slab-out-of-bounds read can happen from smb2_open.
This patch set the minimum value of the name offset to the buffer offset
to validate name length of smb2_create_req().

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ksmbd: corrige slab-out-of-bounds en smb_strndup_from_utf16() Si ->NameOffset de smb2_create_req es menor que el desplazamiento del búfer de smb2_create_req, puede ocurrir una lectura de slab-out-of-bounds de smb2_open. Este parche establece el valor mínimo del desplazamiento del nombre en el desplazamiento del búfer para validar la longitud del nombre de smb2_create_req().
